Explanation :
Neutralization reaction : It is a type of chemical reaction in which an acid react with a base to give salt and water as a product that means it reacts to give a neutral solution.
When baking soda (sodium hydrogen carbonate) base react with lactic acid then it react to gives sodium lactate, carbon dioxide and water as a product.
The balanced chemical reaction will be:

The ionic equation will be:

What happens is it makes water
The wall would absorb extra heat during the day when the sun is out, then release the heat back into the room when the sun goes down.
